I see. I just checked, and that one also works fine here.

The problem occurs with the desktop files nautilus uses to open files. In
particular, what I want is to open text files using

  gvim -c "cd %:h" <file>

What I do is this:

  - Right click on a text file.
  - Select "Open with other application".
  - In the resulting dialog, select "Use a custom command".
  - Type

    gvim -c "cd %%:h" %f

  - Click "Open"
  - Gvim appears, with the error message:

    Error detected while processing command line:
    E344: Can't find directory ":h" in cdpath
    E472: Command failed

Typing

  gvim -c "cd %:h" whatever.txt

on the command line works fine.

(AFAICS, the handling of mime types is done in
libgnomevfs/gnome-vfs-mime-handlers.c, in the function expand_macro,
starting at line 1449. Inspecting the code shows that %% is ignored there,
instead of converted to %)
